Codex session audit shows sandbox confusion can cascade into worse mistakes

Codex session analysis surfaces a common agent failure mode

The author asked Codex to review the last two weeks of sessions and identify where it had to be interrupted, corrected, or redirected.

The key takeaway was that one annoying pattern appears when the agent mistakes a sandbox restriction for a real bug. It then invents a workaround, which can lead straight into another failure mode.

The author still found the analysis useful because it confirmed workflow problems and highlighted where the process can be improved.
